Abstract

|
|
This experiment was performed with the purpose of finding out the effect of simulated acid rain at various pH levels on the morphology and enzyme of Perilla frutescens var. japonica hara. The pH levels of simulated acid rain ranged from pH 2.0 to pH 6.0. The experiment showed the anion concentrations in the order of , , , and , was found out to be the main factor which contributed to the rainwater acidification. A general decrease of growth in Perilla frutescens var. japonica hara growth was shown with the decreas of pH concentration. As acidity increases a definite reduction in the rates of germination, heigth of plant, malate dehydrogenase, and 6-phosphogluconate dehydrogenase was ovserved, but the density of spots on the leaf apex was increased.
